Are you talking about Airport limousine bus? If it is the case, the fee varies according to the destination and the distance(from 5000 to 12000).

It cost you just 6000 won when you travel from inchon airport to kimpo airport. But beyond that must pay more(10000 for most places inside seoul, and 12000 for other cities in kyunggido). Where did you take the bus from?

report him to the ministry of transport or some organization..
one thing korea doesnt need are bus drivers being rude to foreigner businessmen travels soon as they step foot in korea!!! ohh welcome to korea A HOLE!! get off BUS you stupid foreigner!!??
arrrr I dont think so!!!
then again it all comes down to the taxi thing too doesnt it,,
they only pick you up if they want to or if your fair is worth money!
once I told a cop in kangnam station you know after 12 its impossible to catch a cab, the cops direct flow, I stopped the cop and said isnt it illegal for taxis to not pick up customers? they are government service workers arent they not??
cops replies: taxi not take you?
ME" YES..
COP: hang on!
he stands in front of the cab stops him tells me to get in, then the cab driver argues with him alittle until the cop put his foot down!!
ITS ALL ABOUT POWER!!!
even the small bus driver, whom acually has one of the most stressful jobs in any country NEEDS to fell powerful , cant do it to a korean so take it out on the foriegner...
BASTARDS!!

I don't take the airport buses much, but i thought the price differences were dependent on the quality of the bus. 12000 got you a higher quality. It was always 6000 for an older yellow bus, and 12000 for a new bus with leather seats, and a personal TV, no?

strange... Last time I went from incheon to Bucheon I bought my ticket at a booth inside the airport. If I remember correctly, the ticket had the price on it as well. You might give the bus number you want, that's what I did. perhaps the person at the ticket booth just gave you a ticket for a more expensive bus.

Be sure to not take the limousine bus, which can be quite pricey. Check out Incheon Airport's website for bus info as well.

nana... huh...

Yes, but the thing is, I paid 12,000 Won for a good bus, but they told me to go on the cheapy bus.

So I go to the cheapy bus, and when other people pay 6000 Won, I was a little choked.

The fare from Incheon to Ilsan and vice-versa is 7500 won on the 3300 airport bus. I have travelled this one many times and never had a hassle with being overcharged etc. A lot of the airport staff and flight people use this service as its cheaper, and the service runs every half hour. If you take the Airport Limo buses they are dodgy in respect to what fares are charged, so I could not recommend them.
